In the present work, the effect of organic dicarboxylic acid (succinic acid) on lithium sulphate monohydrate was investigated at room temperature. The presence of succinic acid in the solution grown crystals has changed the values of lattice parameters maintaining crystal structure of the host material unaltered. The wide transparency seen in the recorded UV-vis spectrum communicate that the material is applicable to produce NLO efficiency. Mechanical resistivity to the indentation of the grown crystals was estimated through Vickerss microhardness test. Enhanced second harmonic generation efficiency was achieved. All these findings advocate that the grown crystal is suitable for NLO and optoelectronic device fabrication.
